OF CHICAGO, ILLINOIS, A CORPORA- AUTOMATIC oo'uBLs-Ts'EAMlNe MACHINE.,

SPECIFICATION forming partof Letters Patent No. 727,630, dated May 12, 1963. Application filed August 21, 1902. Serial No. 120.441. (No model.)

The object of' my inven'tion is to provide.

an automatic machine of a simple, efficient, and durable construction by means of which the heads of cans may be rapidly, cheaply, and properly double-seamed upon sheet-metal cans or vessels.

My invention consists in'the means I employ to accomplish this result-that is to say, it consistsin the, combination with a continuously-moving carrier having a plurality or series of chucks thereon for receiving and clamping the cans or-vessels and a plurality of sets of double seaming rollers or tools mounted on the carrier, means for automatically reciprocating one of the chuck-disks as the carrier travels, means for operating the seaming rollers or tools, and means for imparting a rotary motion to the seaming rollers or tools in respect to the cans or vessels.

It also consists in combination, with a movable carricr having a plurality of chuck disks or seats for the cans and a plurality of sets of seaming-rollers, of means for automatically feeding or delivering the cans or vessels onto the carrier and means'for automatically discharging the cans or vessels from the carrier.

It also consists in the novel construction of parts and devices and in the novel combi nations of'parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure l is a plan view-'ofa machine embodying my invention. Fig. 2 is a central vertical section. Fig. 3 is a detail side elevation of the mechanism for feeding and discharging the cans. Fig. 4 is a horizontal section on line 4 4 of Fig. 2. Fig. 5 is a detail horizontal section on line 5 5 of Fig. 2. Fig. 6 is a detail horizontal section on line 6 6 of Fig. 2. Fig. 7 is a vertical section online 7 7 of Fig. 6, and Figs. 8, 9, and 10 are detail elevations of the seamingrollers.

In the drawings like letters of reference indicate like-parts in all the figures.

In said drawings, .A represents the frame of the machine. B is a continuously-moving carrier, preferably a rotary turret or wheel. The continuously-moving carrier B has a canreceiving plate or table B, furnished with a series of can-seats or chuck-disks I), having registering pins or devices b for registering the cans with theopposingcan chucking or clamping disks 5*, which are likewise mounted on the carrier above the seats or chuckdisks 6, so as'to clamp the c'an'bctween them.

D D D are a plurality of rotatable seaming-heads mounted on the carrier B and each provided with a set of double-seaming rollers or tools 61 d 01 'each journaled in an adj ustable block D, carried by a radially-movable tool holder or slide D which is reciprocated in the seaming-head 'D by means of the cams f on the vertically movable slide F, with which each seaming-head D is provided for the purpose of moving the seaming-rollers in and out successively, or one after another.

The cam-slides'F'are movedup and down in respect to the seaming-heads D as required to force the seaming rollers or tools against the work as the carrier Brotates continuously by means :of a stationary cam F on the frame of the machine operating through the levers F which are pivoted to the carrier at F and engage grooves of collars-F The seaming-heads'D are rotated in respect :to the cans X, clamped betwcen the chuckdisks 1) b bymeans of spur-gears" d on the shaft 01 of the seaming-heads, which engage a gear 0, which may be stationary, but is preferably rotated in the opposite direction to the carrier B through the worm-gear C and worm C The carrier B is rotated by means of a worm-gear B and worm B To clamp or chuck the cans between the chuck-disks 1) 6 one of these chuck-disks, preferably the lower one, is given a reciproeating movement. This is preferably done by means of a stationary cam B on the frame of the machine engaging a bentlever B pivoted to the carrier and connected to the spindle of the chuck-disk b.

The chuck-disk or can-seat b has a rubber or elastic pad 11 thereon, and the upper chuckdisk b preferably has a ball-bearing connection with the rotary seaming-head D to minimize the tendency of the rotary seaming-head to rotate the can. I prefer to rotate the seaming-heads, in which the seaming-tools are mounted, rather than the can chucking or clamping disks 1) b", as I thus keep the cans from rotating and obviate any tendency to cause the liquid contents thereof to be thrown out by centrifugal action.

The cans are automatically fed or delivered onto the can-seats or chuck-disks b of the continuously-moving carrier 13 from the can-carrier belt K by a movable feeder H, having a series of can-pusher arms h, which engage the cans and move them along a curved guideway 11 onto the flat plate, table, or ring B of the carrier B and against the registering devices or pins 1) of the can seats. The feeder H is preferably given a rotary movement in cooperation with the continuouslyrotating carrier by means of operating-arms h on the feeder, which engage pins or projections on the carrier B, or any other suitable gearing may be employed for connecting the feeder with the carrier; At the time the cans are moved onto the carrier B and disk I) the disk I) is flush with the'can-receiving plate B of the carrier, as is also the case at the time the cans are discharged from the carrier. The cans are automatically discharged from the carrier B as it rotates continuously by means of a can-discharging arm M, which projects in the path of the cans and operates in conjunction with the guide M to deliver the cans upon the can-discharging belt or conveyer N. The can-feed conveyor or belt K travels upon a pulley K, and a plate I1 flush with the convoyer-belt K and carrier B, supports the cans as they are moved by the feeder II from the conveyer K to the carrier 13. A similar plate N, flush with the conveyer N and carrier B, bridges the space between the carrier and said belt or con- Veyer N. The conveyer N travels upon a suitable pulley N".

The operation is as follows: The cans X on the feed-conveyer K are continuously crowded into the guide H at the end ,of said con- Veyer, so that. one of the cans is always in position to be engaged by one of the feederarms h as the feeder H rotates, and thus be moved by the feeder-arm onto the carrier B and against the registering pins or devices I) of the can-seat or chuck-disk Z). As the carrier B continues its rotation the chuckdisk I) is raised by operation of the stationary cam B and connecting bent lever 13 until the can is firmly clamped orchuckcd between the chuck-disks Z) I), the seaming rollers or tools d cl d being at this time retracted. As the carrier B continues its rotation the camslide F is reciprocated in respect to the rotating seaming-head D, and thus forces the first double-seaming roller 61 against the seaming-flange of the can head or cover and curls it over the seaming-flange of the can-body, and as the downward movement of the camslide F continues the second and third seaming-rollers d d are brought successively into operation, and the double seam thus completed, when the further reciprocatingmovement of the cam slide withdraws all the seaming rollers or tools from contact with the can. As the rotation of the carrier 13 continues the chuck-disk b is again brought flush with the can-receiving plate B of the carrier and the can automatically discharged therefrom by the discharge device M. As the carrier is provided with a plurality or series of can clamping or chucking disksb b and with a plurality of seaming heads'and sets of double-seaming rollers, a number of cans are thus being operated upon simultaneously as the carrier rotates continuously, and the work is thus performed automatically and rapidly and cheaply.
